commit 0bf7afa89d6f4592cb76e49ce5dae2b9606920b5

    Full source: updated year on copyright statements to 2021
    
    Having entered 2021, it was necessary to correct the copyright year.
    
    I also noticed that in the French webpage, we still had a notice for GSoC
    2020, so that was also commented.
